Exhibit 99.1

NEWS RELEASE

HECLA REPORTS 2.5 MILLION OUNCES OF SILVER AND

72,995 OUNCES OF GOLD PRODUCTION IN THIRD QUARTER 2018

$200 million revolving line of credit is undrawn at quarter end

FOR IMMEDIATE RELEASE

October 23, 2018

COEUR D'ALENE, IDAHO -- Hecla Mining Company (NYSE:HL) today announced certain preliminary results¹ for the third quarter of 2018.

HIGHLIGHTS 

“Our gold and silver production met our expectations, with gold production increasing due to the addition of two months of production from the Nevada operations and silver production declining due to lower expected grades at Greens Creek,” said Phillips S. Baker, Jr., President and CEO. “We are on track to meet annual production estimates at all operations. At our new Nevada assets, we are focusing on completing enough underground development at Fire Creek so by about mid-2019 we should have consistent production with an expected 50% higher throughput. We have begun the access drift to the Hatter Graben, which could provide the next leg of growth in Nevada. With Hecla’s strong operations and balance sheet management, we don’t anticipate any significant utilization of the line of credit, which is currently undrawn.”

Greens Creek

At the Greens Creek mine, 1.9 million ounces of silver and 11,559 ounces of gold were produced in the quarter. The lower silver and gold production, when compared to the third quarter of 2017, was due to lower ore grades and milled tonnage as a result of mine sequencing. The mill operated at an average of 2,316 tons per day (tpd).

Casa Berardi

At the Casa Berardi mine, 43,981 ounces of gold were produced in the quarter, including 2,767 ounces from the East Mine Crown Pillar pit. The mine produced as expected, with gold production similar to the third quarter of 2017. The mill operated at an average of 3,846 tpd.

San Sebastian

At the San Sebastian mine, 0.5 million ounces of silver and 3,666 ounces of gold were produced in the third quarter. Although silver and gold production were lower compared to the third quarter of 2017, both still met our expectations for the quarter. The mill operated at an average of 432 tpd.

Nevada Operations

At our newly-acquired Nevada operations, 13,789 ounces of gold and 84,145 ounces of silver were produced since the acquisition on July 20. During that period, ore was processed at the Nevada operations at an average of 776 tpd.

Lucky Friday

At the Lucky Friday mine, 31,639 ounces of silver were produced in the quarter compared to 88,298 ounces in the third quarter of 2017, as limited production performed by salaried staff continued during the ongoing strike.

PRODUCTION SUMMARY

Hecla expects to report third quarter 2018 financial results on November 8, 2018.
